The parallel leaf measures 0.15 mm (approximately 0.006 inches) thick, 12.7 mm (approximately 0.5 inches) wide, and 300 mm (approximately 11.8 inches) long. Constructed from tempered steel, the leaf delivers consistent stiffness and resistance to deformation across its full length. This gage is used by machinists, millwrights, HVAC technicians, and other trade professionals who need reliable feeler stock for checking valve clearances, bearing fits, flange gaps, and similar precision tolerances.\u003c\/p\u003e\u003cp\u003eThe 52875 is suited for both shop and field use where a single-thickness feeler leaf is preferred over a folding set. Its parallel leaf profile maintains uniform width from end to end, making it straightforward to use in confined clearance checks on motors, compressors, pumps, and mechanical equipment. The 300 mm length provides enough reach for most standard industrial and HVAC service applications where gap measurement is required during assembly or maintenance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParallel leaf profile maintains uniform 12.7 mm width across the full 300 mm length\u003c\/li\u003e\n\u003cli\u003eTempered steel construction for consistent stiffness and long service life\u003c\/li\u003e\n\u003cli\u003e0.15 mm thickness for fine clearance and gap measurement tasks\u003c\/li\u003e\n\u003cli\u003eStraight leaf format provides easy insertion into tight or confined clearance points\u003c\/li\u003e\n\u003cli\u003eSold as a single leaf for targeted replacement or standalone use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-leaf feeler gage suitable for general mechanical, HVAC, and precision assembly applications requiring 0.15 mm gap measurement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFeeler gages require no installation tools, but the measuring surface and the gap being checked should be clean and free of debris before use to ensure accurate readings. Do not force or bend the leaf into a gap tighter than its rated thickness, as this will permanently deform the leaf and compromise measurement accuracy. Store feeler leaves flat or in a protective sleeve to prevent warping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.15 mm (approximately 0.006 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Width\u003c\/strong\u003e: 12.7 mm (approximately 0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Length\u003c\/strong\u003e: 300 mm (approximately 11.8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Style\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tempered Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538993938738,"sku":"52875","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c14f69ecd71725a35f9c01fbb5df79.jpg?v=1785832136","url":"https:\/\/voomisupply.com\/products\/starrett-52875-feeler-gage-parallel-leaf-tempered-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
